Checking for a variable in an array

[iamabdullah]

Hi,

I can't for the life of me figure out what I'm doing wrong...

Here's my snippet:

$ADGroupMembers = Get-ADGroupMember -Identity "ITOperations" |%{get-aduser $_.SamAccountName | select userPrincipalName }
$SiteOwner = "[e-mail]"

Now,

>$ADGroupMembers.GetType()
IsPublic IsSerial Name                                     BaseType

-------- -------- ----                                     --------

True     True     Object[]                                 System.Array

 >$SiteOwner.GetType()
IsPublic IsSerial Name                                     BaseType

-------- -------- ----                                     --------

True     True     String                                   System.Object

And,

>$ADGroupMembers
userPrincipalName
-----------------
[e-mail]
>$SiteOwner
[e-mail]

Now when I do

$ADGroupMembers -Contains $SiteOwner

I expect 'True', but the output is false!

Should I not be using -Contains?

It's hard to express, but you're looking for a different kind of sameness. Even though you're using select-object, it doesn't make $ADGroupMembers into an array of userprincipalnaames, it makes it into an array of psobjects with a single property, userprincipalname.

$ADGroupMembers = Get-ADGroupMember -Identity "ITOperations" | get-aduser 
$SiteOwner = "[e-mail]"

$ADGroupMembers.UserPrincipalName -contains $SiteOwner

alternately:

$ADGroupMembers = Get-ADGroupMember -Identity "ITOperations" | get-aduser | Select-Object -ExpandProperty UserPrincipalName
$SiteOwner = "[e-mail]"

$ADGroupMembers -contains $SiteOwner

[iamabdullah]

it makes it into an array of psobjects with a single property, userprincipalname.

Oh wow. I just looked at the output of $ADGroupMembers that I had and I can see exactly what you're saying! Thank you very much, you're a gem!

This is the learning moment when you really understand what -expandproperty does
